Assembly / disassembly of the cutting unit,
tensioning of the saw chain (see fig. 2-4)
When used for extended periods of time,
guide bar 1 and saw chain 2 can become
very hot, therefore, you must wear pro-
tective gloves during assembly opera-
tions. This will also reduce the risk of injury from
the cutting edge of saw chain.
• Put the tool on flat ground.
• Unscrew the nuts 29 with the help of the multi-
purpose wrench 25 (see fig. 2.1).
• Move brake guard 4 into the rearmost position and
remove guide bar cover 31 (see fig. 2.1-2.2).
• Install guide bar 1 (see fig. 3) and move it into
the direction of drive gear 32 (this will facilitate the
installation of saw chain 2)�
• Wrap saw chain 2 around drive gear 32, then, place
the drive teeth of saw chain 2 into the slot of the guide
bar 1� Note: saw chain 2 is installed correctly when
the cutting edges are facing forward.
• Install guide bar cover 31 (the tension pin must fall
into the hole in guide bar 1)�
• Screw nuts 29 onto pins 30 and tighten them slightly
by hand�
• Adjust the tension of saw chain 2� Holding the
front of guide bar 1 (see fig. 4.1), rotate chain tension
screw 33 with a screwdriver (see fig. 4.2). To increase
the tension of saw chain 2, turn chain tension screw 33
